lM P'PtOVEM ENT IN STEAM-RADIATORS.

Specification forming part of Letters latent No. 38,154, dated April 14, ISES.

To @ZZ whom t may concern:

Be it known that I, RICHARD TaCRANE, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Steam-Radiators; and I do hereby declare that the following is a full, clear, and exact description thereof, reference boing had to the accompanying drawings and the letters and figures marked thereon, which form part of this specification.

In the said drawings, Figure 1 represents a side elevation of my steam-radiator; Fig. 2, a transverse sectional view at the line m in Fig. 1, and Fig. 3 a plan view of the same in section at the line y in Fig. 1.

The nature of my invention consists in constructing the hollow base of a steam-radiator of two or more chambers or copartments, which said chambers are connected together by means of coiled or U-shaped pipes7 so that when the steam is admitted into one of said chambers the air contained therein is driven out through the said pipes into the opposite copartment, which latter is provided with a stop-cock to prevent the air to escape from the radiator, which stop-cock, after the air has escaped, as aforesaid, is closed to prevent the escape of the steam.

It further consists in providing the partition which divides the base into two chambers, as aforesaid,with an opening or passage at the bottom thereof, and near the inductionpipe for admitting the steam, for the purpose of allowing the water and condensed steam accumulating in the second copartment of the base, to iiow back into the iirst copartment and thence back through said induction-pipe into the steamgenerator.

It further consists in constructing the said base of the radiator with a longitudinal opening between the chambers aforesaid, for the purpose of admitting the air to pass up t-hrou gh the same to come in contact with the radiating-pipes.

To enable those skilled in the art to understand and construct my steamlradiator, I will now proceed to describe the same with particularity.

A in the drawings represents the base of the radiator, and may be constructed of cast-iron or any other` suitable material of sufficient strength to resist the pressure of the steam. The form of said base is clearly shown in the drawings, and may be of a rectangular or tubular form, arranged in such a manner as to leave the oblong opening C between the two chambers, for the purpose of admitting the air to pass up through the same and come in contact with the pipes B. At each end ofthe said base A are arranged the vertical partitions a a', which divide the hollow base into two chambers as eectually as though they were isolated and distinct from each other. These copartments are joined together by the U -shaped pipes, (marked B,) as is clearly shown in the drawings.

In the bottom or lower edge of the partition a is constructed the opening c, through which the Water and steam which condense in the second chamber flows back into the first and out through the induction-pipe into the steamgenerator. The partition a' is provided with no such opening, but closes the end of the base hermetically.

Instead of being constructed as shown, the two chambers may be separate, the opening G extending longitudinally their entire length, in which case the objectof the passager,l could be effected by a short pipeconnecting the two copartments, as the said passage c does when the radiator is constructed as shown; or the passage c may be omitted entirely and the eduction-pipe E, servin g as the outlet for both air and water, may be connected with the steam-generator directly/,or the water may be allowed to run to waste.

The pipesB are of wroughtiron, and may be of any suitable size.

In Figs. 1 and 3 the exterior of the base is represented as being broken away at one end, to show the position of the partition a and the opening c, a. being situated in a similar manner at the other end.

My invention operates as follows: The steam being introduced through the pipe i fills the chamber into which it enters, forcing the air therein through the pipes B into the opposite chamber, whence it is driven out through the eduction-pipe e, and when the air is all driven out the passage e is closed by the stop-cock, to prevent the escape of the steam. As the steam condenses into water, it fiows back into y the rst chamber through the opening c, and

thence into the steamgenerator through the pipe fi.

By the arrangelnentof my improved steamradiator the air is 2111 driven out of said. rasubstantially as and for the purposes delinedietor, and therefore Will admit more steam ated and set forth. and give out more heat than radiators of the 2.
